Victims of a Haitian cholera epidemic said on Wednesday they were filing a lawsuit against the United Nations, while the world body says it is immune from such legal claims.

The
Boston-based human rights group Institute for Justice and
Democracy in Haiti (IJDH) said it will file a compensation claim
against the world body on Wednesday over a cholera epidemic that
has killed over 8,300 people and sickened more than 650,000 since
October 2010.

"The plaintiffs include Haitians and Haitian Americans who
contracted cholera themselves as well as family members of those
who died of the disease," the Institute for Justice and
Democracy in Haiti said in a statement.

No details were given about the amount of compensation the
victims were seeking.

In November 2011, the IJDH filed a petition at UN headquarters
seeking at least $100,000 for the families or next-of-kin of each
individual killed in the epidemic and a minimum of $50,000 for
each victim who suffered illness from the outbreak.

The United Nations, however, said it would not pay hundreds of
millions of dollars in compensation claimed by the cholera
victims.

An independent panel appointed by UN Secretary-General Ban
Ki-moon to study the cholera outbreak issued a 2011 report that
did not hold the Nepalese peacekeepers responsible for the deadly
epidemic.

Ban's spokesman Martin Nesirky said in February of this year that
the United Nations advised the legal representatives of the
cholera victims that "the claims are not receivable pursuant
to Section 29 of the Convention on the Privileges and
Immunities."

A report by the US Centers for Disease Control and Prevention,
however, challenged the UN stance, saying the epidemic was likely
brought to the Caribbean country by the UN peacekeepers when
contaminated sewage was discharged from their living quarters
into a waterway.

Before that, cholera, an infection causing severe diarrhea that
can lead to dehydration and death, had been rare in Haiti.

UN Secretary General Ban Ki-moon launched a $2.2 billion
initiative in December 2012 to rid Haiti of cholera over the next
decade.

Meanwhile, there has been some difference of opinion on the
question of compensation for the Haitian victims.

On Tuesday, a UN official broke with the ranks and argued on
behalf of compensation for the thousands of Haitians involved.

The high commissioner for human rights Navi Pillay, while falling
short of blaming the UN peacekeepers for the epidemic,
nevertheless declared: "I have used my voice both inside the
United Nations and outside to call for the right…of those who
suffered as a result of that cholera be provided with
compensation," Pillay said at an awards ceremony for human
rights activists in Geneva.

UN associate spokesperson Farhan Haq said it was not the "United
Nations' practice to discuss in public claims filed against the
organization."
